ABSTRACT:
A method of manufacturing a container, with a support stand, for bulk material. The method includes the steps of, by extrusion blow molding, forming a vessel having a bottom wall having flash integral therewith and extending therefrom to lie in a plane perpendicular to the plane of the bottom wall, side walls extending upwardly from the bottom wall and oriented such that when the side walls are substantially vertical, the bottom wall being at an angle to the horizontal, an upper wall connected to the side walls, and a support for maintaining the container in a substantially upright position. The support is formed from the flash and includes a first foot and a second foot. In forming the support, the second foot is removed from the flash so as to leave a portion of the flash defining the first foot. The second foot is then removably engaged with the first foot so as to lie in a plane perpendicular to the first foot.
